 Trunnion and barrel compatibility question

I've got an Egyptian kit coming from Cole's and need a barrel for it. Will a Romanian "G" kit barrel fit into the Egyptian trunnion? I'm guessing so––actually hoping so...

TIA!

it'll fit but you'll need to headspace it.

10-4. I'm assuming most barrels are 23mm.

How's about one of these? It would give me an additional compliance part.

Never mind. The gas tube wouldn't work with this barrel.
